Adaptive Weights Smoothing with Applications to Image Restoration
Jöorg Polzehl, Vladimir Grigor'evich Spokoiny · Journal of the Royal Statistical Society Series B (Statistical Methodology) · 2000
Summary We propose a new method of nonparametric estimation which is based on locally constant smoothing with an adaptive choice of weights for every pair of data points. Some theoretical properties of the procedure are investigated. Then we demonstrate the performance of the method on some simulated univariate and bivariate examples and compare it with other nonparametric methods. Finally we discuss applications of this procedure to magnetic resonance and satellite imaging.
